This example demonstrates how to load and display a CSV dataset using D3 utilities within a React application. It fetches a list of CSS named colors from a GitHub gist, tracks the loaded data in React state, and shows a summary message with file size, row count, and column count. The code uses `d3.csv` for parsing, `d3.csvFormat` for size calculation, and React's `useState` and `useEffect` hooks to manage the asynchronous data loading. The visualization is purely text-based, rendering the summary in a large font.
